分析:(1)中的540÷36可根據(jù)除法的性質(zhì)變?yōu)?40÷9÷4,將96拆分為6×16進(jìn)行計算;
(2)可根據(jù)一個數(shù)減兩個數(shù)的和等于用這個數(shù)分別減這兩個數(shù)的減法性質(zhì)進(jìn)行計算;
(3)可將17.5×0.18根據(jù)乘法的性質(zhì)變?yōu)?.75×1.8后再運(yùn)用乘法分配律進(jìn)行計算;
(4)可根據(jù)乘法分配律進(jìn)行計算;
(5)根據(jù)四則混合運(yùn)算的運(yùn)算則計算即可:先算乘除,再算加減,有括號的要先算括號里面的.
點(diǎn)評:當(dāng)算式中同時含有中括號與小括號時,要先算小括號里面的,再算中括號里面的.
